Key Parameters for Selecting RF Inductors

RF inductor selection involves a number of key parameters including, mounting (surface mount or through-hole), inductance value, current rating, DC resistance (DCR), self-resonant frequency (SRF), Q factor, and temperature rating. While small size is typically desired, the laws of physics limit how small an inductor can be for a given application. Inductance value and current rating are the chief determinants of size. Once they have been calculated, other parameters can be optimized.

Making History: Advanced System in a Package Technologies Enable Direct RF Conversion

RF data conversion systems are experiencing rapid changes as ADC and DAC performance specifications and form factors, along with new sensor technologies (Rx & Tx), continue to advance. One system level design problem has been consistent throughout—balancing the implementation tradeoffs between the analog and digital circuitry for maximum software/system flexibility (from sensor to the digital processing units’ input/output).

Measuring Millimeter Wave Materials for 5G and Advanced Sensing

With the rapid growth of wireless communication and sensing, there has been increased development of technologies at ever higher frequencies or smaller wavelengths. For example, high bandwidth communication addressed in the 5th Generation (5G) cellular network standards has motivated the opening of spectrum within the K and Ka bands (18-40 GHz). Whether repurposing existing lower frequency materials or developing new higher-frequency optimized materials, component developers need accurate material properties to use in their component designs.
